Calories Burned Running Calculator

Estimate calories burned during a run from body weight, duration, and average speed. A quick first-pass for runners tracking energy expenditure; uses a simplified linear formula rather than full MET-based equations.

Fitness

Protein Intake Calculator

Estimate daily protein need (grams) from body weight, training intensity, and goal (maintain, build, or lose weight). Targets evidence-based ranges for active people: 1.2–2.2 g protein per kg body weight depending on activity and objective.
